Description

{Impact point detection method of shooting system with bullet ball pellet}

The present invention relates to a method of detecting an impact point of a shooting system for BB bullets, and more particularly, a BB bullet that analyzes an accurate impact point by applying computer vision technology to an analog shooting system that aims and strikes a target with a BB bullet and displays it on a screen. It relates to a method for extracting impact points of a dragon shooting system.

Conventional shooting systems, which are configured for the user to aim and hit a target with a simulated firearm, require accurate determination of the impact point.

In recent years, due to the development of advanced equipment, a system that can determine the shooting score by analyzing the impact point more precisely as well as eliminating expendable bullets mounted and fired on the simulated firearm by adopting a laser in the shooting market has been established. It is being serviced.

However, users who enjoy the shooting system are equipped with bullets capable of physically hitting targets, such as a BB, and are highly responsive to the conventional shooting system fired from a simulated gun.

Conventional shooting systems in which such simulated firearms are equipped with bullets such as BB bullets and are fired require a real shooting distance between the target and the user, and this makes it difficult for the user to check the impact point on the target at a distance.

Accordingly, in the present invention, an impact point on a target physically hit is accurately detected and displayed through a monitor located near the user.

As a prior art, in the laser shooting system for extracting the impact point of Korean Patent Publication No. 10-0460522, and the method of extracting the impact point in the laser shooting system, fire according to a signal from the control room against a target fixedly installed at a distance from the launcher. In the artillery shooting system consisting of a direct firing cannon, the target location can be photographed and stored in the microcomputer to set the reference coordinate value for artillery shooting, and read by a computer to check whether it matches the previously stored score pattern reference value. A shooting means configured to construct a scoring pattern reference coordinate value program for accuracy analysis when shooting a gun, and to automatically move and adjust a preset reference coordinate value as much as the change position of the display when there is a change in the recognized display; By establishing a wireless communication network with the photographing means, it is possible to wirelessly communicate the image data with the photographing means, and the target location recognized by the photographing means is set as a reference coordinate value for shooting and a previously stored score It is possible to construct a program for analyzing the hit rate of shooting while controlling to match the pattern value, and to analyze the hit rate of each shooter by comparing and judging the image target transmitted from the shooting means with the programmed score pattern reference value Analysis processing means; And an output means for converting data processed by the hit ratio analysis processing means into data. It is described as a target hit ratio analysis system.

As another prior art, the system and method for calculating the location of the impact point of Korean Patent Application Publication No. 10-1624416 include: first and second cameras respectively acquiring images around the impact point; A first server generating coordinates of a first image of an impact point from an image acquired by the first camera; A second server generating coordinates of a second image of an impact point from the image acquired by the second camera; And a position calculating device for calculating the position of the impact point based on the first image coordinate and the second image coordinate.

However, the method of detecting the location of the impact point through the conventional configuration as described above is an application of a method of determining the difference between the image of the previous target location and the image of the current target location by acquiring only the image of the target location. There was a disadvantage in that the position of the impact point could not be detected if the difference between images did not occur due to the exact re-strike of the bullet.

Therefore, the present invention was invented to solve the above problems, and when shooting a physical bullet such as a BB bullet, by analyzing the trajectory of the physical bullet by applying a computer vision programming technique, the exact location of the impact point is detected. It aims to display to the user through the monitor.

In order to achieve the above object, the method of detecting the impact point of the shooting system for non-biton bombs according to an embodiment of the present invention, while the camera is mounted toward the target from the shooting position, and the physical bullet is fired from the simulated firearm to reach the target. In order to capture an image, it is possible to obtain a trajectory image of a physical bullet by making the camera image wider than the target area.

It is characterized by analyzing and determining the exact impact point on the target site through comparison between the trajectory of the BB, which is a physical bullet acquired through the camera, and the target site image determined as the impact point.

In the method of detecting an impact point of a shooting system for non-bit bullets according to an embodiment of the present invention, by applying computer vision programming, the trajectory of a physical bullet is analyzed to detect the exact location of the impact point, thereby providing an effect that can be displayed to a user through a monitor.

In addition, even if the bullet is accurately re-strikeed on the part where the impact point is formed by the previous hit, the position of the impact point is accurately detected and displayed even if there is no difference between the previous target location image and the current target location image.

In addition, the method for detecting the impact point of the bullet shooting system according to the embodiment of the present invention is an objective and scientific method by accurately analyzing the trajectory of the bullet through the slope calculation of the position analyzed as an inter-frame bullet in the trajectory image of bullets configured for each frame. It provides the effect of displaying the impact point based on the normal operation.
